Recently I was able to compare heads made by Waukeshe engine company. If you look closely you can identify several differences in these two heads. I do not know which one is the earlier of the two.

Just a swag but the one with priming holes is early?
I have no proof, but I would think that the priming holes would be removed in later production. Dan

I have one of each Jack & always was under the impression the primer cup model was earlier.

I've owned two and both were the early type with priming cup provisions.

There was actually 3 versions. Here is an early one. It had a different plain combustion chamber.
